Sorry, I had that in an earlier version of the patch but it was not
needed in the final one. I reverted this bit in r265336.

BTW, I tested cleaning this up a bit by either always reading symbol
names early or late. Amusingly they are both slower. I will still work
a bit on the "always late" patch, but we might really be in a sweet
spot for when to read global/local names.

Cheers,
Rafael
